London, Jan 19: A son took his dead mother on a 58-km bus journey home after she died on the way back from a day out, a media report said Thursday.

The 88-year-old woman is believed to have passed away in the wheelchair on her way back to Preston from Lancaster, the Daily Mail reported. 

Police said her son, 52, then waited at Preston bus station with his dead mother before boarding a second bus for the journey back home in Chorley Monday.

When the bus arrived at Chorley, a security guard saw the man with his mother and became suspicious. He called the police.

Officers stopped him in a nearby street and an ambulance was called but the woman was already dead. Police said the death was not being treated as suspicious. 

"It is very tragic. This man has lost his mother and was struggling to know how to deal with it," a police spokesman said.
